no biggie, the precomp is easy to make, right click precompose the exposure repair one. make sure you click 'leave attributes' so you don't move the 'set grey' effect from exposure repair comp.

the new hue precomp uses an adjustment layer set to hue for effect-hue. you can also add curves set to color, and curves set to luma for flat images.

the shadow/highlight code upgraded to include b/w you'd paste into Shadow Amount under effect 'Shadow/Highlight' under layer '8mm ships.mov 2' in comp 'Final output'.

r = comp("exposure repair").layer("background").effect("Step 3: Set Gray")("Color")[0]*2;
g = comp("exposure repair").layer("background").effect("Step 3: Set Gray")("Color")[1]*2;
b = comp("exposure repair").layer("background").effect("Step 3: Set Gray")("Color")[2]*2;



mr=Math.log(r);
mg=Math.log(g);
mb=Math.log(b);

a=mr+mg+mb;
if(a<0.01)
{a=0.01}
dd=(0.8-(a/3))+(comp("FINAL_OUTPUT").layer("MASTER CONTROL SLIDERS").effect("Exposure Compensator 0-default")("Slider")/100);

if(dd>(comp("FINAL_OUTPUT").layer("MASTER CONTROL SLIDERS").effect("[] Gamma Clamp at gamma 20-default")("Slider"))/20)
{
roll=(comp("FINAL_OUTPUT").layer("MASTER CONTROL SLIDERS").effect("[] Gamma Clamp at gamma 20-default")("Slider")/20);
linear(roll,0,dd,100,0);
}
else
0;
